Purse State Park, Maryland, USA, Aquia Formation 38.43 N, 77.26 Wfound in material provided by
John Thanetian, Paleocene
Benthonics
the classification of these planispiral and trochospiral specimens as Cibicides is based upon:
Cushman, J, 1951: Paleocene foraminifera of the Gulf Coastal region of the United States and adjacent areas, U.S. Geological Survey professional paper 232, Plate 19
Any hint of newer literature on paleocene benthonics from the East Coast of the USA is highly appreciated
